259 dnl per the autoconf manual, we can speed up autoconf somewhat by quoting
260 dnl the great gob of text. Thus it's not processed for possible expansion.
261 dnl Just make sure the brackets remain balanced.
263 dnl Since Emacs can't find matching pairs of quotes, boundaries are
264 dnl indicated by comments.
268 ### If you add support for a new configuration, add code to this
269 ### switch statement to recognize your configuration name and select
270 ### the appropriate operating system and machine description files.
272 ### You would hope that you could choose an m/*.h file pretty much
273 ### based on the machine portion of the configuration name, and an s-
274 ### file based on the operating system portion. However, it turns out
275 ### that each m/*.h file is pretty manufacturer-specific - for
276 ### example hp9000s300.h is a 68000 machine;
277 ### mips.h, pmax.h are all MIPS
278 ### machines. So we basically have to have a special case for each
279 ### configuration name.
281 ### As far as handling version numbers on operating systems is
282 ### concerned, make sure things will fail in a fixable way. If
283 ### /etc/MACHINES doesn't say anything about version numbers, be
284 ### prepared to handle anything reasonably. If version numbers
285 ### matter, be sure /etc/MACHINES says something about it.
287 ### Eric Raymond says we should accept strings like "sysvr4" to mean
288 ### "System V Release 4"; he writes, "The old convention encouraged
289 ### confusion between `system' and `release' levels'."
